Components Two-Dimensional Spatial Light Modulator
The EXULUS-HD1 reflective two-dimensional spatial light modulator (SLM) are based on a liquid crystal on silicon (LCoS) technology. The Exulus SLM provides high-resolution, high-speed phase modulation with minimal fluctuations, making it ideal for use in a wide range of applications such as optical trapping, beam steering and shaping, femtosecond pulse shaping, adaptive optics, display and imaging, and holography.
The EXULUS-HD1 includes a built-in SLM panel with 1920 x 1080 resolution, 6.4 μm pixel pitch, 93 % fill factor, and a 12.5 x 7.1 mm2 active area. With operation from 400 nm to 850 nm, it offers a phase stroke of 2π at 633 nm (standard mode) and 5.7π at 532 nm (extended mode). The EXULUS-HD1 is driven by a standard digital video interface (HDMI) signal and provides a refresh rate of 60 Hz in standard mode and 180 Hz in the frame boost mode. The industry-leading configuration parameters and easy-to-use software interface facilitate the performance of diversified applications ranging from stand-alone functions to integrated research-grade systems.
The Exulus SLM is bundled with a software graphical user interface (GUI) that provides complete control over the device and supports different driving modes including full frame, image input, video input, Fresnel lens, diffraction, and computer-generated holography (CGH). The CGH mode also allows tilting and focusing effects to be superimposed onto a pattern to achieve combined functionalities.
The built-in SLM panel provides independent horizontal and vertical tilt adjustment of ±3.2°. Highly flexible customized versions of the Exulus that have the panel separated from the control unit and a 4K resolution (3840 x 2160) version are also available.
